En sTATEs PATENT oEEio GEORGE S. FOSTER, 0F PUEBLO, COLORADO.

' Be it known that I, GEORGE S. Fos'rER, a

tion.

:ithe class of shock citizen of the United States, residing at Pueblo,

in the county of Pueblo and State of Colorado, have invented new and useful Improvements in Shock-Absorbers for'Vehicles, of which the following is a specifica- The invention relates to pneumatic cushioning devlces,

vehicle will be elast-ically separated, so that limparting the same to the vehicle body, the

` on the travel ,of the vehicle, vibrations' will be absorbed, thereby relieving the body of the vehicle from shocks and jars incident to the travel of the said vehicle.

Another object of the invent-ion is the provision of a device of this character in which the body of a vehicle will be elastically supported upon the running gear, so that all shocks and jars will be relieved, without devlcebeing readily and easily applied to the vehicle, and when used will obviate the l necessity of the employment of cushion or pneumatic tires ordinarily used.

A further :object of the invention is the l provision of a device of this character which is extremely simple in construction, thoroughly .reliable and eiicient in operation,

and inexpensive in manufacture.

With these and other objects in View, the invention consists in the construction, combination and arrangement of parts, as will ybe hereinafter more fully described, illusytrated in the accompanying drawings, and

' pointed out in the claim hereunto aprpended.

In the drawings: Figure 1 is a agmentary side elevation of a vehicle, showing the device applied thereto constructed in accordance with the invention. Fig. 2 is an 'enlarged fragmentary vertical longitudinal sectional view through the device. Fig. 3 is a vertical transverse sectional view .through the device.

Similar reference characters indicate corresponding parts throughout t-he severalV views of the drawings.

hicle, in this instance, 4ofthe automobile type, 6 the ground wheels, 7 the axle support-ing the ground wheels, and 8 the usual elliptical' shaped spring which is clipped or otherwise mounted upon the axle 7 1n the usual manner.

Carried by the upper half of the spring 8- 1s theI shock absorber, comprising a substantially elliptical shaped frame, including a plurality of upp'er and lower sections 9 and 10, respectively, the adjacent ends 11 of t-he sections being reduced in width and connected by means of suitable hinged joints 11 for affording the necessary flexing of the frame, the upper and lower sections 9 and 10 being dished in cross section, so as to form 'proper seats for retaining a substantially cigar shaped air bag or casing 12 which may be made from any suitable ma- Y terial, and is formed with an inlating tube 13 which permits the attachment of a pump (not shown), whereby the bag 12 may be or inflated the required degree for absorbing shocks and jars incident to the travel of the vehicle over uneven surfaces in the ground.

The frame for supporting the air bag 12 is secured to the upper half of the spring S by means of the usual clips 14, Fixed to the frame 5 and projecting outwardly therefrom, at the side thereof, is a bracket 15, the latter beingbolted or otherwise secured to the frame, as will be seen. It is, of course, understood that the frame with the air bag 12 mounted therein may be interposed between the axle 7 and the spring 8,l without lrequiring anyV alteration in the spring or the vsaid axle, should the occasion demand.

What isolaimed is:

In a shock absorber, an elliptical shaped frame including a plurality of hinged sections, said sections having their adjacent ends reduced in width, the to-p and bottoni stretches of said frame being longitudinally channeled at -the inner sides and an inflated bag seated in said channels and substantially filling the frame.

vIn testimony whereof I aiix my signature inpresence of two witnesses.
